Dumbarton House stood witness to the birth of the American Republic as the government settled into the newly established built in 1799 on the heights of Georgetown, Dumbarton House was home of the first Register of the U. S. Treasury, Joseph Nourse, who resided here with his family and servants - free, indentured, and enslaved - from 1804-1813. Dumbarton House's period rooms and rotating exhibitions tell the stories of the early city of Washington and offers visitors a view of what life was like in the earliest days of our nation's capital.

In 1928, the National Society of the Colonial Dames of America (NSCDA) purchased the property as its national headquarters and opened the museum to the public four years later. As the headquarters of the NSCDA, Dumbarton House shares the stories of women in preservation. The NSCDA, through its Corporate Societies, owns, maintains, or supports over 80 historic sites and collections around the country.


Visitors to Dumbarton House return in time to when Joseph Nourse, first Register of the U.S. Treasury, and his wife Maria, made their home here, between 1804 and 1813. The first floor of the home is decorated and furnished to reflect their tastes, and the early history of Washington and Georgetown. In addition to our first floor period rooms, our second floor galleries include special exhibits around the history of D.C. and the NSCDA.

STEM in the Historic House provides visitors with examples of how science, technology, engineering, and math help us gain a deeper understanding of our past. For instance, STEM is involved in examining historic building plans, producing historic wallpaper, conducing microscopic paint analysis and painting restoration, aiding in frame construction and crate manufacturing, and in casting and printing methods.

The Exchange 2019|3 explores the Chinese export trade and the use of tariffs in the Federal Period. Visitors will gain an understanding of early American trade with foreign nations and how that relates to the present.
